Assuming the owner is telling the truth, he had a choice to make: he could offend the complaining customers by telling them that he did not need their bigotry and that they need no longer patronize his establishment because he respected the police; or he could do what he did and chase away the police instead.
It appears he made the wrong choice.
He could have kept his stupid mouth shut, an opportunity too few people too infrequently avail themselves of. I still believe he was expressing a personal preference, not relaying customers’ concerns.
So...the restaurant owner has cop hating patrons & he sided with them rather than tell them to take their business elsewhere because he respects the police? Was that it?
